DollarSignEngine
Dynamically evaluate and interpolate C# expressions at runtime with ease, leveraging a powerful script execution engine.
Introduction
The DollarSignEngine is a robust C# library designed to simplify the process of dynamically evaluating and interpolating expressions at runtime. Ideal for applications requiring on-the-fly script execution, it offers developers the flexibility to inject variables and execute complex C# expressions seamlessly.
Features
- Dynamic Expression Evaluation: Evaluate C# expressions dynamically at runtime, with support for interpolation and complex logic.
- Parameter Injection: Easily pass parameters into expressions for dynamic evaluation.
- Support for Complex Types: Effortlessly handle complex data types, including custom objects, collections, and more.
- Comprehensive Error Handling: Provides detailed exceptions for compilation and runtime errors to ease debugging.
Installation
The library is available on NuGet. You can install it using the following command:
dotnet add package DollarSignEngine
Usage
Below are some examples of how to use the DollarSignEngine to evaluate expressions dynamically.
Evaluating Simple Expressions
var result = await DollarSign.EvalAsync("1 + 1");
Console.WriteLine(result); // Outputs: 2
Interpolating Strings with Parameters
var parameters = new Dictionary<string, object>
{
{ "name", "John" }
};
var result = await DollarSign.EvalAsync("Hello, {name}", parameters);
Console.WriteLine(result); // Outputs: Hello, John
Handling Complex Data Types
var person = new { FirstName = "Jane", LastName = "Doe" };
var parameters = new Dictionary<string, object>
{
{ "person", person }
};
var result = await DollarSign.EvalAsync("Person: {person.FirstName} {person.LastName}", parameters);
Console.WriteLine(result); // Outputs: Person: Jane Doe
